Inter- and Intramolecular Addition Reactions of Electron-Deficient Alkenes with Alkyl Radicals, Generated by SET-Photochemical Decarboxylation of Carboxylic Acids, Serve as a Mild and Efficient Method for the Preparation of γ-Amino Acids and Macrocyclic Lactones
Inter- and intramolecular additions of alkyl radicals, generated by SET photochemical decarboxylation reactions of free carboxylic acids, to electron-deficientalkenes take place under mild conditions as part of efficient routes for the formation of N-Boc γ-amino acids and macrocyclic lactones.

Sequential Intermolecular Radical Addition and Reductive Radical Cyclization of Tyrosine and Phenylalanine Derivatives with Alkenes via Photoinduced Decarboxylation: Access to Ring-Constrained γ-Amino Acids
Sequential radical addition to alkenes and reductive radical cyclization of phenylalanine and tyrosine derivatives via photoinduced decarboxylation furnished ring-constrained γ-amino acids under mild conditions. A variety of alkenes such as acrylamides and acrylic esters could be employed in the photoinduced radical cascade cyclization. The yields of the ring-constrained γ-amino acids are dependent
